His fellow trainer, 20-year old Keltie Byrne, had slipped and fallen into the orca tank. Byrne was an exceptionally strong swimmer but she was no match for the aquarium's killer whales.

"She tried to get back out and the other girl tried to pull her up, but the whale grabbed her back foot and pulled her under," eyewitness Nadine Kallen told CNN affiliate CTV in 1991. "And then the whales -- they bounced her around the pool a whole bunch of times, and she was screaming for help.

"They tried to grab her with sticks, but they couldn't get her," Kallen said. "And she finally didn't come up any more."
